PSpice-equivalent parts PSpice-equivalent parts respond to a differential input and have double-ended output. These parts reflect the structure of PSpice E and G devices, thus having two pins for each controlling input and the output in the part. Table 6-4 summarizes the PSpice-equivalent parts available in the part library. PSpice-equivalent ABM parts can be classified as either E or G device types. The E part type provides a voltage output, and the G device type provides a current output. The device's transfer function can contain any mixture of voltages and currents as inputs. Hence, there is no longer a division between voltage-controlled and current-controlled parts. Rather the part type is dictated only by the output requirements. If a voltage output is required, use an E part type. If a current output is necessary, use a G part type.
